These rivers are inland rivers in an arid area, which originate from glaciers in the headwaters and disappear in the desert area. The basins could be divided into three areas based on characteristics of water quality as well as the topography and the vegetation, those are mountain, oases and desert areas. High salinity was found in both basins, and the salinity was the highest in the desert area of both basins. Generally, a river in an arid area must be concentrated in salinity as it flows because of strong evaporation effect. In the mountain to oases areas of the Heihe river basin, however, the river was diluted with groundwater of low chemical concentration, and the contribution of groundwater to the total discharge would be approximately 80%. The discharge of the main stream of the Shiyang river is completely dammed up in the mountain area. Therefore, the chemical compositions in the desert area should be similar with that of a tributary in the oases area, but different from that of the main stream in the mountain area.","subitem_description_type":"Abstract"}]},"item_2_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究ノート","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"2070","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Akiyama, Tomohiro"}]},{"nameIdentifiers":[{"nameIdentifier":"2071","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Fujita, Koji"}]},{"nameIdentifiers":[{"nameIdentifier":"2072","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakawo, Masayoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"2073","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Abe, Yutaka"}]},{"nameIdentifiers":[{"nameIdentifier":"2074","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tsujimura, Maki"}]}]},"item_2_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水文・水資源学会"}]},"item_2_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.3178/jjshwr.17.61","subitem_relation_type_select":"DOI"}}]},"item_2_relation_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://jlc.jst.go.jp/JST.JSTAGE/jjshwr/17.61","subitem_relation_type_select":"URI"}}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-1389","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"1349-2853","subitem_source_identifier_type":"ISSN"}]},"item_2_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Japan Society of Hydrology and Water Resources"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"名古屋大学大学院環境学研究科"},{"subitem_text_value":"総合地球環境学研究所"},{"subitem_text_value":"筑波大学大学院生命環境科学研究科"},{"subitem_text_value":"筑波大学地球科学系"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"秋山, 知宏"}],"nameIdentifiers":[{"nameIdentifier":"2065","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤田, 耕史"}],"nameIdentifiers":[{"nameIdentifier":"2066","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中尾, 正義"}],"nameIdentifiers":[{"nameIdentifier":"2067","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安部, 豊"}],"nameIdentifiers":[{"nameIdentifier":"2068","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻村, 真貴"}],"nameIdentifiers":[{"nameIdentifier":"2069","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-30"}],"displaytype":"detail","filename":"17_61.html","filesize":[{"value":"774 Bytes"}],"format":"text/html","licensetype":"license_note","mimetype":"text/html","url":{"label":"17_61.html","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/593/files/17_61.html"},"version_id":"8acbf319-c82f-48ae-aa0f-d7a1a887a59b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"乾燥域","subitem_subject_scheme":"Other"},{"subitem_subject":"黒河流域","subitem_subject_scheme":"Other"},{"subitem_subject":"石羊河流域","subitem_subject_scheme":"Other"},{"subitem_subject":"塩分濃度","subitem_subject_scheme":"Other"},{"subitem_subject":"主要溶存成分","subitem_subject_scheme":"Other"},{"subitem_subject":"Arid area","subitem_subject_scheme":"Other"},{"subitem_subject":"Heihe river basin","subitem_subject_scheme":"Other"},{"subitem_subject":"Shiyang river basin","subitem_subject_scheme":"Other"},{"subitem_subject":"Salinity","subitem_subject_scheme":"Other"},{"subitem_subject":"Chemical composition","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"中国甘粛省および内蒙古自治区における内陸河川の水質特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"中国甘粛省および内蒙古自治区における内陸河川の水質特性"}]},"item_type_id":"2","owner":"1","path":["14","136"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-06-14"},"publish_date":"2013-06-14","publish_status":"0","recid":"593","relation_version_is_last":true,"title":["中国甘粛省および内蒙古自治区における内陸河川の水質特性"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-19T03:41:34.654074+00:00"}
